I consider myself a "beginer". i would suggest leaving the foundry work for later. start off with Your basic bladesmith-blacksmithing hammer skills. Do a lot of research on the internet and the library on methods and practices of bladesmithing....AND most of all, PRACTICE.
I built my first gas forge for about 20$.. Using materials from second hand building stores and garage sales, yard sales ect... just keep in mind that there will definately be mistakes made along the way.
